Application filed June 6, 1919.

To all whom it may concern:

Be it known that I, VVILLIAM F. MOON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Yarn-Speck Removers, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The present invention relates to a device for removing lumps of fiber or what are commonly called specks from yarn or thread, previous to its use in a spinning or weavin machine.

An 0 ject of this invention is to provide a device of this character which will include means for positioning the speck, and means co-acting with -the positioning means to sever the speck from the thread.

\Vith the above and other objects in View which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, I have illustrated two complete examples of the physical embodiment of my invention con structed according to the best modes I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a side view of one form of my invention, parts being broken away to more clearly illustrate the details of construction.

more clearly illustrate the details of construction.

Fig. 7 is a top plan view thereof, parts being broken away and in section for the purpose of illustrating details of construction.

Fig. 8 is a side view of one end of the device, parts being broken away and in section, and

Fig. 9 is a view, part in section and part in elevation, said view being taken on the line 9 9 of Fig. 6.

Referring now to the drawings, and more particularly to Figs. 1 to 5 inclusive, the numeral 10 designates generally the frame of the machine which has a plurality of pairs of upstanding spaced apart yoke shaped standards or arm members 11; 12 a pair of drive shafts mounted in the frame and provided with a pair of meshed gears 13, and 14 a pulley driven from any suitable source of power and adapted to rotate the shafts 12.

In the drawings, I have illustrated a plurality of speck removing devices, each of which successively acts upon the thread to remove any specks therefrom, so that if the first device does not remove the speck, it will be removed by another of the devices.

Each of these speck removing devices is mounted in the adjacent yoke members 11, and consist generally in means for presenting the speck in a position in which it may readily be severedfrom the thread or yarn by the cutters or shears hereinafter described.

The means for presenting the speck in position for removal consists of a bed-block 15 secured to, the frame 10 by means of a screw 16 intermediate the yoke members 11 as best shown in Fig. 4. The bed block 15 is in the form of a stationary knife and co-acts with the reciprocating cutting means, to be later described. The yarn or thread 17 is guided through the frame member 10 by means of suitable guiding members 18 and 19, located at each end of the frame,

'and the thread, in its passage through the frame engages the top of the bed block, and should the speck be on the under side of the yarn,'the same will be turned or positioned to the side, there to be severed from the thread as will be later described.

As the bed block 15 is insufficient in itself to retain the thread uponits top surface, in

that the thread would become disengaged therefrom, as will be obvious, I so construct my cutting means as to cooperate with the bed block to retain the thread in engagement with its top surface which is essential to insure the positioning of the speck. The cutting means consists of a pair of vertical knives 20 disposed one on each side of the bed block 15, and each secured to the top of a block 21 by directing the upper end thereof laterally as at 22, and securing the same by means of fastenings 23. Each knife 20 has formed on its lower end a slightly inclined shearing edge 2f which terminates in a depending lug or ear 25 which provides the means for retaining the yarn upon the bed block 15, irrespective of the position of the knife.

In order that the knives may be resiliently urged to engagement with the bed block 15, each block is urged outwardly from its retainer 26 by means of an extensile spring 27, confined therein and impinging against the block 21. The movement of the block 21 on the spring 27 is limited by means of a bolt 28 which has one end thereof in threaded engagement with the block 21. and the other end thereof projecting outwardly of the retainer 26 and provided with locking nuts 29. The portion of the bolt 28 disposed in the retainer 26 is capable of movement therein as will be obvious, and the bolt 28 provides the means for semirigidly securing the knife 20 with the retainer 26.

The retainer 26 is slidably confined between the adjacent yoke members 11 and removably retained in position by means of a removable plate 30 whicli,-with the lateral y projecting flanges 31 formed on the yoke members 11, provides guiding means for the retainer 26. The retainer 26 is adapted to be reciprocated by means of a cutting rod 32 having its upper end journaled between a pair of spaced depending cars 33 carried by the retainer 26, and its lower end provided with bearings 34: and journaled by an eccentric 35 fixed to the adjacent shaft 12.

As the shaft 12 is rotated, a reciprocating movement will be imparted to the retainer 26 and consequently its knife 20, whereby the knife will, with the bed block 15. sever the speck which may be positioned to the side by the bed block 15 from the thread. The opposed eccentrics 35 on the shafts 12 are so arranged that the knives 20 of each pair will be oppositely reciprocated in order that a continuous cutting action is obtained throughout the entire passage of the yarn or thread through the machine. The eccentrics 35 are also arranged in order that the cutting knives on one side of every other pair of cutting means will be operated in unison.

As the thread passes through the machine, it is successively acted upon by the plurality of pairs of cutting means, and the thread is continuously guided upon the bed block by means of the depending lugs 25 which will be of sufficient length to insure the engagement of the same with the bed block 15 when the knife 20 is at its forward limit of movement. Thus the thread 17 is also guided through the frame by the depending lugs well as by the members 18 and 19.

By providing a plurality of speck removing devices, the complete removal of specks from the yarn is assured, for as will be understood by those skilled in the art to which an invention of this character appertains, the yarn, owing to the tension which it is under, turns throughout its passage through the machine by reason of its being twisted and woven, and so should a speck be upon the upper surface of the yarn when it passes over the first bed block 15, the yarn will have turned during its passage through the short distance between the first bed block and the second, and thus the speck will be presented to the bed block. .Vhen the speck is presented to the bed block, it is naturally moved or positioned to one side and thus severed from the thread when the knife 20 descends.

Refe ring now more particularly to Figs. 6, 7 8 and 9, I employ the same principles as hereinbefore described, by using a plurality of pairs of rocking members in place of the reciprocating members 20. This form of my invention comprises generally a longitudinal frame member 36 having formed thereon a plurality of opposed pairs of spaced upwardly extending centrally apertured lugs or ears 37, and to each car 37 is pivotally secured a rocking arm 38 by means of a pivot bolt 39 having its inner end in threaded engagement with the aperture of the ear 37.

The rocking arms 88 disposed on one side of the frame 36 are adapted to be rocked by means of a pitman t0 pivot-ally secured as at 41 to a connecting rod 42 having pivoted thereto as at 43, the lower ends of the rocking arms 38 disposed on one side of the frame 36, whereby all of the arms 38 on one side of said frame will be rocked in unison. The pitman 10 is oscillated by means of an eccentric fttt carried by a shaft 45 adapted to be rotated by a pulley t6 connected with any desiredsource of power.

As best shown in Fig. 7, the rocking arms 38 disposed on the other side of the frame 36 are also connected in a like manner by means of a connecting rod 42 and pitman 40. As

best shown in Fig. 8, the eccentrics M- are so positioned on the shaft d5 as to insure the oppositely rocking of the arms 38 of each pair whereby a continuous cutting movement is effected.

The upper end of each rocking arm 38 is formed with. a cylinder or centrally apertured cap 47 in which is slidably mounted a hollow sleeve end 48 of a retaining block 49. The retaining block 49 is normally urged downwardly or outwardly of the cylinder 47 by means of an extensile spring 50 disposed in the central bore of the sleeve 48 and having its upper end impinged against a plate 51 engaging the lower end of a tension adjusting screw 52. Secured to the inner face of the retainer 49 by means of a screw 53 is a rocking knife member 54 which has its lower end yieldingly held in engagement by means of the spring 50 with a bed block 55 secured to the frame 36 intermediate an opposed pair of ears 37 by means of a screw 56.

The pivot 39 of the arm 38 has its center in alinement with the top surface of the bed block 55 to insure the constant engagement of the knife 54 with the bed block 55 when the knife is rocked. As before described, the knives of each opposed pair are oppositely rocked and a continuous cutting action is had. The yarn 17, as in the other form of my invention is guided through the frame 36 by means of guiding members 18 and 19, and also by means of the knives 51 and bed block 55.

The opposed pairs of knives 54 are spaced apart exactly the thickness of the thread, and as the thread passes over the bed block 56, the speck, if it is on the under side of the thread, will be moved or positioned to one side and there severed by means of the knives 54 when they are rocked. The yarn is successively acted upon by each pair of cutting means as in the other form of my invention, and consequently further description thereof is thought unnecessary.

From the foregoing description, it would be apparent that the rocking members 54 serve to, in a sense, crush the speck from the yarn, and to insure this crushing action, the spring 50 is adjusted to the proper tension by means of the adjusting screw 52.
